Here is why, I think: a mountaintop is a place which is static; what is wanted is a dynamic state, a way of moving, including moving in being.
Here is, I think, a better metaphor: different religions are like different types of dancing. No educated person would confuse a waltz with samba. One is very formal, elegant, measured. The other completely exuberant and spontaneous. But both, at root, are cultivating the same pleasure in movement, the same freedom, the same root spontaneity.
And in a sense, is trusted spontaneity not perhaps the defining attribute of freedom? Is it not one of the things we long for most? Is it not in some ways HOW we create what we call our selves?
Can anyone doubt that some Viennese, however repressed and cold in the rest of their worlds, took profound, deep, exuberant pleasure in this recreation?
What one seeks in dance, in many respects, is consistent across cultures. You seek altered states, pleasure, a sense of connection, a sense of balance and rhythm, and even joy.
And does it matter what dance form brings these feelings? All can succeed, and all can fail, particularly if excessive focus is placed on external form rather than internal motion, connection with the sensation of pleasure in movement.
I have personally seen people make samba miserable, by trying to do it exactly right.
As with so many things, look to un-self conscious children to see the proper spirit.
